Q1 of 168 Page 216

Using differentials, find the approximate value of each of the following up to 3 places of decimal.

Consider y = .


Let x = 1 and Δx = -0.4. Then, we get



= √0.6-1


= √0.6 = Δy + 1


Now, dy is approximately equal to Δy and is given by:




= -0.2


Therefore, the approximate value of is 0.8.
